The truck 0411 applications with a 4x crank sensor still use a distributor. You're not going to get CNP from that setup. It would require a 24X wheel...

Good call Steve.. and the video proves it all lol

On the new wiring harness there's a wire labeled AC Pressure which I haven't connected to anything. Please forgive me, what do you mean when you...

Awesome! Thank you BCC: AHWZ 7639 Just the few steps that DaveW had me take, ie: 3 wire O2 Sensor etc has the vehicle sounding and...

I'm sorry, but I seem to be having trouble seeing the relay or any of the wires attached to it. Maybe you have a wiring diagram and can match up...

That’s what i’d presumed. Other than it setting DTC’s i couldn’t see how it could alter the pcm code. It’s not piggybacking any input either. ...

You have the wiring diagramm from SOOB, there you can see pin B8 is coming from A/C pressure switch. Try to give it a minus signal alternatively a...

Agreed Steve ��

Thanks for looking this over for me. I'll run a log again, I must have somehow stopped the logging sooner then I thought.

total and complete bullshit. the box probably doesn't even have circuity in it. there's no known way to externally control fueling (or timing or...

Ah, i thought it was a generic unit rather than application specific. Ta Mitch

It re maps your fueling tables MAF ect to a preset in that is built in to the unit to a leaner fuel mixture. It's a external power programmer

It requires 1.5 seconds of cranking without a cam signal to set a code p0342 or p0343. If it syncs within this time......no code will be set. Codes...

Thank you both for answers. @JimCT_9C1 is it possible to share your bin with 3.73 gear ? I would like to compare and try to understand the logic...

Working through test tool interface code at the moment. I have found the download sequence in mode $34. Interesting that controller $10 and...

I'm sorry, but I seem to be having trouble seeing the relay or any of the wires attached to it. Maybe you have a wiring diagram and can match up...

Okay I think I understand it a bit better now. Another way of doing RPM math is there are 60,000 milliseconds in a minute. So 60,000/RPM =...

I doubt that would be at all related. I'm fairly confident I identified the source of the stumble as an oversight I made in transitioning correctly...

I think I finally got the surge at deceleration issue resolved today. Minimum idle air was misadjusted. Fortunately my re-man and bored throttle...

Your IAC will rise up too. Eventually O2 and closed loop will change too. If you don`t want idle setting over programming, why don`t you mount a...

Hey spfautsch, I noticed a youtube post where a guy did an EFI connection conversion, but had problems above 5000rpm with the crank sensor. His...

I'm not at the programming stage of my TBI education lol. I'm still trying to figure that all out. the blurry photo had me squinting to see what you...

This is interesting for sure, but it appears that the company is still in the development stage.

Wouldn't this cause the computer to continue making adjustments? I thought raising the idle would need to be made via programming ?

Thank you for the additional info!! Is it safe to assume that the relay on the firewall to the right of the Fuel Pump relay is the THM400 relay? If...

Thanks for the answers. And the xdfs. Do you know if the 2 bar cos is on this site or another, ive been looking but haven't found one.

You can raise the idle with the torx screw on the bottom right of the TB behind the plug (pry or drill it out).

Thinking about a system like this for some of our parking lot bound shuttle buses: https://www.fallbrooktech.com/accessory-drives/alternator
